Vulnerability identifier: #VU8329

Vulnerability risk: Low


CVE-ID: CVE-2017-1000251


Exploitation vector: Local network

Exploit availability: Yes

Vulnerable software:
Linux kernel
Operating systems & Components / Operating system
linux_kernel (Debian package)

Vendor: Linux Foundation

The vulnerability allows an adjacent attacker to execute arbitrary code on the host system.

The weakness exists due to a stack-based buffer overflow in the processing of L2CAP configuration. An adjacent attacker can submit a specially crafted Bluetooth protocol, trigger memory corruption in the Bluetooth stack and execute arbitrary code in kernel space.

Successful exploitation of the vulnerability may result in host system compromise.

Install update from vendor's website.

Vulnerable software versions
